Vokera boiler: what does 04 error mean?

My Vokera linea boiler heats water for about 10 minutes before stopping, and then flashing 04. If switched off for a while, it will then heat water again for about 10 minutes before stopping again. This has been happening for about 4 months and is slowing getting worse: time before stopping is getting shorter and shorter - Any idea what's wrong?

the 04 code on the linea 24/28 means low water pressure or poor flow , if the water pressure is ok at 1.5bar on the gauge then its either a problem with the diaphragm, the microswitch or the pump !!!!!!!!
